Scenic view of

Oak Ridge is a city in Tennessee. Oak Ridge was created as secret city during World War II as part of the Manhattan Project. In Oak Ridge, thousands worked in secrecy to enrich the uranium used in the bombs dropped on Hiroshima and Nagasaki, Japan. The city is no longer secret, but it has a rich history worth exploring, and a strong bent toward science and technology. Oak Ridge is Appalachia and the nuclear age rolled into one, a great city to check out.
